position legend of a stacked bar plot

Question

I am trying to create a stacked bar plot, but I cannot position the legend so that it does not overlap any of the bars. I have tried adjusting the margins, setting xl

Answer 1

How about this:

library(RColorBrewer)

barplot(
    y,
    xlim=c(0, ncol(y) + 3),
    col=brewer.pal(nrow(y), "Paired"),
    ylab="My Variables",
    legend.text=TRUE,
    args.legend=list(
      x=ncol(y) + 3,
      y=max(colSums(y)),
      bty = "n"
    )
)
